Greatest Threats to Earthworks

Farming practicesThe Greatest Threats to Earthworks Today

Modern no-till farming techniques do no further damage to ancient earthworks that have already been degraded by two centuries of plowing.

However, development and construction on earthwork sites destroy even the underlying foundations of these great monuments, obliterating any traces that might have held clues about this mysterious ancient culture, and further desecrating a places held sacred by many Americans.

When construction happens on prehistoric earthwork sites, the last vestiges of these ancient ceremonial complexes are lost forever.

Yet there are no laws protecting earthworks on private property in Ohio. That is why the Heartland Earthworks Conservancy attempts to purchase these sites when they come up for sale.




How can concerned citizens help?

We have fallen heirs to the most glorious heritage a people ever received, and each one must do his part if we wish to show that the nation is worthy of its good fortune.
